The present invention relates to a steering wheel base for gaming applications according to claim 1, a full system according to claim 13 comprising a steering wheel and a steering wheel base according to the invention and a method of connecting a steering wheel to a steering wheel base according to the invention according to claim 14.
A steering wheel base is used to simulate steering behavior for gaming applications, like automobile race simulations or similar applications. Therefor it comprises a steering wheel shaft that is connectable to a steering wheel, wherein the steering wheel base is configured to direct simulated forces to the steering wheel shaft and thus to the steering wheel and, at the same time, to read the steering movement of the steering wheel and thus of the steering wheel shaft and to transmit this to the gaming application. In addition the wheel base is connected to the electronics of the steering wheel. To attach the steering wheel to the wheel base, a quick coupling system is used with elements on the side of the wheel base and the steering wheel.
A steering wheel base with such a quick coupling system is known from European Publication No. EP 4 041 615 A. It ensures that the steering wheel is attachable to the steering wheel base only in the correct orientation. This improves the simplicity and properity of the connection between the steering wheel base and the steering wheel. However, the versatility of using such a steering wheel base is limited.
It is therefore the object of the present invention to provide a steering wheel base with improved versatility of use.
A solution of the object is provided with a steering wheel base according to one embodiment of the invention. A steering wheel base for gaming applications comprises a steering wheel shaft, an attachment component, which is fixed to the steering wheel shaft to rotate with the steering wheel shaft and that is configured such that the steering wheel base is directly electrically connectable to electronics of a steering wheel via an electric plug-in contact of the attachment component, and a system comprising a first mechanical quick coupling element and a second mechanical quick coupling element, wherein the first mechanical quick coupling element and the second mechanical quick coupling element are interchangeably fixable to the attachment component into a fixed position and are adapted for different steering wheel side coupling elements of the steering wheel to provide mechanical quick coupling between the steering wheel base and the steering wheel.
The steering wheel base makes it possible that steering wheels with different wheel side coupling elements can be coupled to the steering wheel base in an advantageous and simple way. This improves the versatility of the usability of the steering wheel base.
Further, the port to the electronics of the steering wheel is similar for several steering wheels. Accordingly, it is advantageous that the electric plug-in contact of the steering wheel base is part of the attachment component, which is not interchangeably, as the user does not have to disconnect any internal electronic connections when adapting the steering wheel base for a different steering wheel. The first mechanical quick coupling element and the second mechanical quick coupling element are purely mechanical components that can also be interchanged by amateur users in a quick and efficient way.
Advantageous embodiments of the present invention are the subject of the dependent claims.
According to a particularly preferred embodiment, the attachment component comprises a first engagement element and the first mechanical quick coupling element and the second mechanical quick coupling element each comprise a second engagement element, wherein the first mechanical quick coupling element and the second mechanical quick coupling element are only fixable to the attachment component in the fixed position, when the first engagement element engages the second engagement element. This ensures the orientation of the first mechanical quick coupling element and the second mechanical quick coupling element with respect to the steering wheel base in the fixed position. Preferably, the first engagement element is formed as a projection and the second engagement element is formed as a groove or vice versa. In this way the engagement elements can be designed in a simple way.

This facilitates the connection of the electric plug-in contact and the electronics of the steering wheel.
In another preferred embodiment, the outer periphery of a portion of the protrusion, preferably of the electric plug-in contact, is shaped such that the first mechanical quick coupling element and/or the second mechanical quick coupling element can be inserted onto the protrusion only in a specific orientation.

According to a preferred embodiment, the protrusion comprises at least one snap-fitting element, preferably two at opposite positions, at its sheath surface, which is configured to engage with a counterpart on the sleeve part of the first mechanical quick coupling element and/or the second mechanical quick coupling element. This allows the first mechanical quick coupling element and/or the second mechanical quick coupling element to be fixed to the attachment component in a simple and non-laborious way. Preferably, the counter part of the sleeve part is configured as an opening accessible from the outside of the sleeve part. This facilitates the release of the snap-fitting connection between the at least one snap-fitting element and the counterpart.
According to another preferred embodiment, the protrusion comprises a threaded hole in its sheet at its sheath surface, which is configured such that a fastener is screwable into the threaded hole through an opening leading into the cavity in an outer wall of the first mechanical quick coupling element and/or the second mechanical quick coupling element to secure the first mechanical quick coupling element and/or the second mechanical quick coupling element in the fixed position in a specific orientation. This also allows the first mechanical quick coupling element and/or the second mechanical quick coupling element to be fixed to the attachment component in a simple and non-laborious way.
In particularly preferred embodiment, the first mechanical quick coupling element and the second mechanical quick coupling element each comprise coupling engagement elements on an outside of the sleeve part that serve to mechanically quick couple the steering wheel side coupling elements of the steering wheel to the steering wheel base.

In another preferred embodiment, the sleeve part of the respective first mechanical quick coupling element and second mechanical quick coupling element is configured such that the steering wheel side coupling element of the steering wheel is only couplable to the steering wheel base in a defined orientation. This simplifies the correct fixation of the steering wheel to the Steering wheel base. Preferably, an outer contour of the sleeve part of the respective first mechanical quick coupling element and/or second mechanical quick coupling element is formed in such a way, that the steering wheel side coupling element of the steering wheel is only couplable to the steering wheel base in a defined orientation, wherein the outer contour is preferably axis symmetrical to the defined orientation and is not point-symmetric.

The figures show an embodiment of a steering wheel base 1 for gaming applications according to the invention. The steering wheel base 1 comprises a steering wheel shaft that is mounted as part of an electrical motor inside a steering wheel base casing 3.

As a different embodiment, the steering wheel shaft can also be mounted inside a belt device inside a steering wheel base casing 3.
Further the steering wheel base 1 comprises an attachment component 2 that is fixed to the steering wheel shaft to rotate with the steering wheel shaft.
